Design a User-defined robot of your choice (or you can use the URDF file) and enable the LIDAR Scanner so that any obstacle placed on the path of the light scan will cut the light rays. Visualize the robot in the Gazebo workspace, and also show the demonstration in RViz. (NB: Gain knowledge on wiring URDF file and .launch file for enabling any user-defined robot to get launched in the gazebo platform.) SLAM : One of the most popular applications of ROS is SLAM(Simultaneous Localization and Mapping). The objective of the SLAM in mobile robotics is to construct and update the map of an unexplored environment with the help of the available sensors attached to the robot which will be used for exploring. URDF: Unified Robotics Description Format, URDF, is an XML specification used in academia and industry to model multibody systems such as robotic manipulator arms for manufacturing assembly lines and animatronic robots for amusement parks. URDF is especially popular with users of the Robo
Processors in Embedded Systems A Processor in an Embedded Systems contains two essential parts * Control Unit - Which fetches the instruction from the system memory * Execution unit Arithmetic and Logic Unit is also the part of Execution Unit It performs Data Transfer and data conversion operations Types of processors General Purpose Processors (GPP) Microprocessor Microcontroller Digital Signal Processors (DSPs) Media Processors useful for sound and image processing applications Application Specific System Processors The processors which are relevant to a particular application like Digital TV HDTV decoders Set Top Boxes DVD Player Important considerations while selecting a processor Instruction Set Maximum bits in an operand like (8 or 16 or 32 bit) Clock frequency in MHz and processing speed in MIPS (Millions of Instructions per second) ability to solve the complex algorithms used in meeting the deadline for thei
